Description

Humidification Air Cleaner {Apparatus for both humidification and air cleaning}

The present invention relates to a humidified air purifier.

An air purifier is understood as a device for inhaling and purifying contaminated air and then discharging the purified air. For example, the air purifier may include a blower for introducing external air into the air cleaner and a filter capable of filtering dust or bacteria in the air.

Humidifiers are understood as devices that inhale, humidify, and then discharge air to provide moisture to the air. Conventional humidifiers are classified into a vibrating type that atomizes water in the diaphragm and discharges it into the air, and a natural evaporating type that evaporates in the humidification filter. The spontaneous evaporative humidifier is a humidifier filter humidifier that rotates the disc by using a driving force, the disc humidifier spontaneously evaporates water on the surface of the disc in the air, and the evaporator spontaneously evaporated by the air flowing in the humidifying medium wet water Are distinguished.

In recent years, humidifying air purifiers having a humidifying function added to an air purifier have been developed. In the case of humidifying air cleaners, hygiene requires the user to periodically clean or replace the filter and bucket.

Related documents include KR10-2017-0051276A (hereinafter referred to as Prior Document 1).

However, the humidifier air purifier disclosed in the above document 1 has a relatively complicated internal structure. In addition, the prior art document 1 has a problem that it is difficult to easily operate the water tank to be filled with water from time to time.

In this regard, KR10-1225981 B1 (hereinafter referred to as Document 2) discloses a technique for easily pulling out or pulling out a bucket and a tray in which the bucket is installed to the side of the air cleaner.

In the prior document 2, a rotator (or drive gear) rotating with a driving unit, a humidifying gear (or aberration) rotating under the rotational force of the rotator, and a lifter (or collecting unit) provided around the humidifying gear are provided. Is provided, the lifter is disclosed a configuration to wet the humidification filter provided therein by spraying the water stored in the tray by the rotation of the humidification gear.

In the preceding document 2, the humidifying gear is provided to slide in the lateral direction to engage the rotator. This coupling method has the advantage of achieving stable meshing between gears.

However, from the time the humidifying gear is in contact with the rotator to the moment when the humidification gear is completely drawn in, the rotator may be forcibly rotated by a predetermined rotational angle by the force of the user pushing the humidifying gear. Therefore, the humidification gear of the prior document 2 is not smooth in the intake and drawout, noise generated by the contact between the gears and the forced rotation of the motor.

In addition, the draw-in of the humidifying gear is completed only when the user provides a force equal to or greater than a threshold value for forcing the rotation of the motor, so that the process of combining the humidifying gear and the rotator has a disadvantage in that it is not smooth or smooth.

As a result, the coupling of the humidifier gear and the rotator disclosed in the prior document 2 has problems such as noise generation, relatively large force required by the user, and a rough and uneven coupling process.

On the other hand, the humidifying gear of the prior document 2 is located below the air circulation hole for guiding the air suction to the blowing fan in order to contact with the water of the tray. Therefore, the rotator engaging with the humidification gear is also positioned to block the upper portion of the air circulation hole.

In addition, the humidification gear is supported by the humidification gear support of the front, the air circulation hole of the blowing fan is sucked to the rear air is arranged. According to this, the humidification gear is vibrated in the front and rear direction by the flow of air sucked into the blowing fan, thereby generating a vibration noise.

As a result, the humidification gear support part disclosed in the prior document 2 has a problem of preventing the vibration of the humidification gear.

On the other hand, the bucket located on one side of the humidification gear of the prior document 2 is installed in the reservoir formed by the tray. The reservoir is provided to communicate with the humidification gear.

However, in the prior document 2, there is no motivation for recognizing a problem about noise generated when water is supplied from the water tank to the reservoir of the tray (hereinafter, 'water supply noise'), and means for minimizing the water supply noise. There is no suggestion.

As a result, the bucket and tray disclosed in the prior document 2 has a problem that it is difficult to minimize the water supply noise.

FIG. 18 is a comparative graph illustrating a test force required according to a relative position when the humidification filter driving gear and the filter gear are coupled according to an embodiment of the present invention.

When a conventional general gear other than the filter gear 388 and the humidification filter driving gear 355 according to the above-described embodiment is provided, the user is forcibly forced to the filter gear between the gears of the humidifying filter driving gear 355. The gear teeth of (388) must be pushed in to locate. At this time, the force pressurized by the user has a problem that the filter gear may be much larger than when the filter gear is drawn in the lateral direction of the humidification filter drive gear.

The relative position (%) is based on the case where the rear face of the gear of the filter gear 388 and the front face of the gear of the humidification filter drive gear 355 are in contact with each other. That is, the case where the rear end of the filter gear teeth 388b and the front end of the driving gear teeth 357 abut is defined as a reference (0%).

The right plus direction from the reference (0%) is defined as the relative position at which the filter gear 388b is rotated in the first direction (clockwise) to contact the drive gear 357. The left minus (-) direction from the reference (0%) is defined as a relative position where the filter gear 388b is rotated in the second direction (counterclockwise) and the drive gear is in contact with the 357.

For example, the relative position +50 (%) can be understood as a case in which one filter gear 388b is rotated clockwise so that the two filter gears 388b are completely positioned between the two. In this case, the force N necessary for the user to press the door assembly 200 may be minimum.

The relative position -50 (%) can be understood as a case in which one filter gear 388b is rotated counterclockwise so that the two filter gears 388b are completely positioned between them. Therefore, the force N required at the relative position +50 (%) and the relative position -50 (%) is the same.

The necessary force N may be defined as an acceptance criterion for the force required for coupling when the case where the above-described filter gear is drawn in the lateral direction of the humidification filter drive gear. In one example, the acceptance criteria may be 5 (N).

When the filter gear and the humidification filter driving gear which do not comply with the above-described embodiment of the present invention are provided (conventionally), the maximum force is required at the relative position 0 (%). At this time, the maximum force may be 20 (N) or more.

On the other hand, when the filter gear 388 and the humidification filter drive gear 355 according to an embodiment of the present invention is provided (invention). It can be seen that the necessary force N according to the relative position is kept substantially constant within the acceptance criteria 5N.

That is, according to the filter gear 388 and the humidification filter driving gear 355 according to the embodiment of the present invention, the filter gear 388 and the humidification filter driving gear 355 are easily engaged with each other in the front-rear direction. There is this.

Accordingly, the user may press the door assembly 200 with a relatively small force to couple the filter gear 388 and the humidification filter driving gear 355 to be accurately engaged.
